Assuming it is an 80 sided REGULAR polygon, each exterior angle is 360/80 degrees = 4.5 degrees. So each interior angle = 180 - 4.5 = 175.5 degrees.

What is an 80 sided shape called?
An 80 sided shape is called a Octacontagon.
Two angles of a triangle measure 15 degree and 85 degree what is the measure for the third angle?
80 degrees(We're talking strictly about interior angles here.)
Which angle measures 80 degrees?
Any angle between 0 degrees and 90 degrees is called an "acute" angle.
What is the name of the 80 sided polygon?
octacontagon is an 80-sided polygon
What is the measure of one angle of a regular convex 80 gon?
Exterior angle = 360/80 = 4.5 degrees. Interior angle = 180 - 4.5 = 175.5 degrees. And, a regular polygon has to be convex.
Why cant a regular polygon have interior angles measuring 80 degrees?
The formula for the size of the interior angle for a regular polygon is 180°(n-2)/n, where n is the number of edges, i.e. a whole number. If we set this equal to 80° then we get 180°(n-2)/n=80°180°n-360°=80°n100°n=360°n=3.6which isn't a whole number. So no regular polygon can have an interior angle of size 80°.
What is a 80 sided polygon called?
Octacontagon
What is the name of a polygon with a sides of 30 40 50 60 70 80 90 100 1000 10000?
I find the name "30-sided polygon", "40-sided polygon", etc. just fine.
Interior angle of a convex quadrilateral?
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
IFan exterior angle of a triangle is 110 degrees and one of the interior opposite angle is 30 degreesfind the other two angles of the triangles?
70 and 80 degrees
A triangle has one angle of 80 degrees and another of 60 degreesHow many degrees must there be in the third angle?
Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.
What is the value of x if a triangle has two 50 degree angles?
If you meant x to be the third interior angle, x would equal 80, because the sum of all three interior angles of a triangle equals 180. So 80+50+50=180
What is the supplement of a 100 degree angle?
180-100=80 degree angle

The supplement of an 80 degree angle is an 100 degree angle.
